摘　　要：辽河东部晚古生代时期,随着华北地台的不断抬升,海水从北向南不断退出研究区。在此过程中发育了陆表海台地相、有障壁海岸相、三角洲相和河流相。本溪组时期,全区广泛发育五套石灰岩,其中本溪灰岩可以作为区域对比的一个标志层。太原组和山西组时期,全区煤层广泛发育,含煤地层具有多层次多旋回的特点。With the constant uplift of the North China platform,the sea continuesto exit from the north to south during the late Paleozoic period in the east area of Liaohe.In this process,there have developed some facies,such as the epicontinental platform phase,barrier coast phase,delta facies and fluvial facies.Five sets of limestones are widely developed in the region during the Benxi period.The Benxi limestone could be used as a marker bed regional comparison.During the Taiyuan and Shanxi period,coal is widely developed in this area;there are multi-level and multi-cycle characteristics in the coal-bearing strata.
